Recently, the applications in which AC power
supplies are used have changed.
Edwards Lifesciences is recalling EV1000A, EV1000NI, EV1000CS EV100 Clinical Platforms due to the potential for fluids to leak into the AC power
outlet on both the EV1000A and the EV1000NI clinical platforms, the FDA reported.
Conventionally, medium voltage AC power
distribution units are widely used in heavy machinery and mining industries but due to increasing loads on data centers, many data centers operators are adopting medium voltage AC power
distribution units to meet their industry-size demands.
DC power from the modules is converted to AC power
at the inverter.
Obviously there's a number of factors involved in making the decision to move to AC power
. "All of the original equipment was DC with motor-generator [MG] sets," Lindborg said.
The first two primarily introduce personnel safety hazards while the third significantly contributes to AC interference by continuously coupling AC power
to an adjacent pipeline through the presence of an alternating magnetic field associated with operation of the high-voltage AC (HVAC) system.
Thick walls and heavy insulation make wiring for AC power
expensive and time-consuming.
With its 85 to 264VAC wide input and an IEC 320/C14 AC inlet mating with different types of AC power
cords, the power adapters can be used worldwide.
The recalled item was specifically the AC power
cord marked "LS-15" which was distributed with Hewlett-Packard and Compaq notebook and mini notebook computers, as well as with AC adapter-powered accessories such as docking stations.
Because of this, doubly-fed induction generators can be directly connected to the AC power
network and remain synchronized at all times with the AC power
Scientists at the University of Minnesota have developed a reactor that uses a simple high-frequency AC power
supply to generate high-intensity electric fields in liquid food, which will then inactivate microorganisms.
